fragments and the IDS will not spot the true nature of the fully assembled datagram. The

intensive task for IDS to reassemble all fragments itself, and on a busy system the packet
will slip through the IDS onto the network. What is this technique called?

Anonymizer sites access the Internet on your behalf, protecting your personal information
from disclosure. An anonymizer protects all of your computer\’s identifying information while
it surfs for you, enabling you to remain at least one step removed from the sites you visit.
You can visit Web sites without allowing anyone to gather information on sites visited by
you. Services that provide anonymity disable pop-up windows and cookies, and conceal
visitor\’s IP address.
These services typically use a proxy server to process each HTTP request. When the user
requests a Web page by clicking a hyperlink or typing a URL into their browser, the service
retrieves and displays the information using its own server. The remote server (where the
requested Web page resides) receives information on the anonymous Web surfing service
in place of your information.
In which situations would you want to use anonymizer? (Select 3 answers)
A. Increase your Web browsing bandwidth speed by using Anonymizer
B. To protect your privacy and Identity on the Internet
C. To bypass blocking applications that would prevent access to Web sites or parts of sites
that you want to visit.

TCP SYN Flood attack uses the three-way handshake mechanism.

2. System B sends a SYN/ACK packet to victim A.
3. As a normal three-way handshake mechanism system A should send an ACK packet to
system B, however, system A does not send an ACK packet to system B. In this case client
B is waiting for an ACK packet from client A.
